"Pet-sitter Dixie, a former sheriff's deputy on leave after the death of her husband and daughter, finds a corpse in the gatehouse of a mansion, but leaves the body for someone else to find. Her new client, a mysterious scientist wracked by pain, owns the mansion, and Dixie ends up caring for him and his pet iguana as she tries to solve the murder and juggle her conflicting feelings for heartthrob Lieutenant Guidry and seductive attorney Ethan Crane."

This was my least favorite of the series. I still like the characters, but I didn't like the biological warfare and research part of the plot.
